@volts.wtf, @brownmjason.bsky.social nailed it! @energysmartwv.bsky.social did a great job explaining load matching on the @heatpumped.org podcast. Heat pumps do it great, oversized furnaces are terrible at it (especially in shoulder season, aka when it’s only kinda cold) youtube.com/shorts/ZrNNr...

My EV6 is the best car I’ve ever owned (and there’s no way it could have been close if it was an ICE car)

What’s wild is how little the pitch has changed — only the tech has.
Then: electric resistance heat.
Now: heat pumps (2–4× more efficient), induction, solar + batteries.
The idea is 70+ years old. The tools finally caught up.

In the 1950s, GE and Westinghouse backed a national program where builders earned a Gold Medallion for homes that were 100% electric: heat, hot water, cooking, lighting.
It was massive — 900+ utilities, 180 manufacturers. This was mainstream housing.
Ronald Reagan was the spokesman!

I think something like this is even better suited for this type of temporary apartment installation: m.youtube.com/watch?v=Ihl4...
